most annoying videogame levels

just a forum that i came up with after playing an annoying mission in dragon ball xenoverse but what are some levels in videogames you all have played that just irritated the crap out of you. for this particular entry of mine i'll list a few parts from xenoverse

Buu Buu! Majin Buu- at one point you are fighting alone and are surrounded by 6 smaller majin buu's that all gang up on you

a mission in the beerus saga where you fight beerus and whis with trunks on your team....but everytime i try it they immediatly gang up on me. and they both have 2 HP bars and semi auto guards

I can think of some good examples. The first Crash Bandicoot game had some very difficult levels, such as the ones where you get from one side of a long bridge to the other, two levels known as Lost City and Sunset Vista, and there's also two levels that involve climbing up the castle. The second castle climb, known as Stormy Ascent was so hard, it was scrapped, and I think that the castle climbing levels are the most unforgiving, and the checkpoint is so far, it's placed at halfway into the stage, and both of them are very long.
